<p class="docText"><a name="idd1e85387"></a><a name="idd1e85390"></a><a name="idd1e85395"></a>In <a class="docLink" href="ch11.html#ch11">Chapter 11</a>, we learned the basics about threads and thread synchronization. In this chapter, we will learn the details of controlling thread behavior. We will look at thread attributes and synchronization primitive attributes, which we ignored in the previous chapter in favor of the default behaviors.</P>
<p class="docText">We will follow this with a look at how threads can keep data private from other threads in the same process. Then we will wrap up the chapter with a look at how some process-based system calls interact with threads.</P>
